The central question addressed in this book is this: How is the process of adaptation different if the members of a population live clustered in small groups instead of being homogenously distributed like grass on a lawn? The field is called ‘evolution in subdivided populations’ or ‘adaptation in metapopulations.’ The book covers a diverse array of topics, including group selection, family selection, kin selection and sexual selection, as well as speciation genetics, maternal and paternal genetic effects, and host-symbiont co-evolution. These topics are addressed using a combination of conceptual, theoretical, field and laboratory studies and a diversity of living systems ranging from the laboratory model of flour beetles in the genus, Tribolium, to willow leaf beetles, to other animals, plants and microbes.Less

Societies must choose how they wish to deal with climate change. Not doing anything or pursuing ‘business as usual’ is likely to lead down a path that will have devastating consequences for many people, especially the world’s poor. Using a focal lens of coral reef fisheries, upon which millions of people depend on for their livelihood, this book provides a tool box of options for confronting the consequences of climate change through building local-scale adaptive capacity in societies and improving the condition of the natural resources. Building adaptive capacity will require strengthening appropriate aspects of a society’s flexibility, assets, learning and social organizations. They ways of doing this are diverse and will, of course, depend on existing local capacities and needs. Improving the condition of resources tends to require restricting or limiting society’s actions. These two broad concepts, of building social capacities and limiting certain types of resource use, interact in complicated ways, requiring coupled actions. One of the central themes of this book is that adaptation solutions are context dependent, determined in part by aspects of local resource conditions, adaptive capacity, and exposure to climate change impacts, but also by people’s history, culture, and aspirations. This book develops a framework to help provide governments, scientists, managers, and donors with critical information about the local context and develop nuanced actions that reflect these local conditions. This information can help to identify key opportunities and narrow the range of potential adaptation options that may be suitable for a particular location.Less

Understanding the mechanisms driving biological diversity remains a central problem in ecology and evolutionary biology. Traditional explanations assume that differences in selection pressures lead to different adaptations in geographically separated locations. This book takes a different approach and explores adaptive diversification—diversification rooted in ecological interactions and frequency-dependent selection. In any ecosystem, birth and death rates of individuals are affected by interactions with other individuals. What is an advantageous phenotype therefore depends on the phenotype of other individuals, and it may often be best to be ecologically different from the majority phenotype. Such rare-type advantage is a hallmark of frequency-dependent selection and opens the scope for processes of diversification that require ecological contact rather than geographical isolation. This book investigates adaptive diversification using the mathematical framework of adaptive dynamics. Evolutionary branching is a paradigmatic feature of adaptive dynamics that serves as a basic metaphor for adaptive diversification, and the book explores the scope of evolutionary branching in many different ecological scenarios, including models of coevolution, cooperation, and cultural evolution. It also uses alternative modeling approaches. Stochastic, individual-based models are particularly useful for studying adaptive speciation in sexual populations, and partial differential equation models confirm the pervasiveness of adaptive diversification. Showing that frequency-dependent interactions are an important driver of biological diversity, the book provides a comprehensive theoretical treatment of adaptive diversification.Less

This book aims to present different voices and perspectives on the adaptive landscape, its past, present, and future position in evolutionary biology. Chapters have been written by scientists in different fields, including ecology, evolution, developmental biology, genetics, history of science and philosophy. The idea for this book came a few years ago, as the 80-year anniversary of Sewall Wright's classic paper was approaching rapidly (2012). This seemed to be an excellent opportunity to summarize the state of the art of the adaptive landscape. The hope is that this volume won't mark the end of the scientific discussions about the adaptive landscape, but rather a new beginning. And finally, it is hoped that if the adaptive landscape will not survive another 80 years, it will hopefully be replaced by an even better concept or metaphor that will push evolutionary biology forward and increase knowledge about adaptation, speciation, and the origins and preservation of biodiversity on this fragile planet.Less

Aging has long since been ascribed to the gradual accumulation of DNA mutations in the genome of somatic cells. However, it is only recently that the necessary sophisticated technology has been developed to begin testing this theory and its consequences. This book critically reviews the concept of genomic instability as a possible universal cause of aging in the context of a new, holistic understanding of genome functioning in complex organisms resulting from recent advances in functional genomics and systems biology. It provides a synthesis of current research, as well as a look ahead to the design of strategies to retard or reverse the deleterious effects of aging. This is particularly important in a time when we are urgently trying to unravel the genetic component of aging-related diseases. Moreover, there is a growing public recognition of the imperative of understanding more about the underlying biology of aging, driven by continuing demographic change.Less

This book synthesizes the findings from the NSF-funded Arctic LTER project based in Toolik Lake, Alaska, a site that has been active since the mid-1970s. The book presents research concerning the core issues of climate-change science, and addresses the treeless regions of arctic Alaska, as well as the adjoining boreal forests. The book examines both terrestrial and freshwater-aquatic ecosystems, and their three typical habitats: tundra, streams and lakes. The book provides a history of the Toolik Lake LTER site, and discusses its present condition and future outlook. The chapters create a multidisciplinary survey of the Alaskan arctic ecosystem. Topics include glacial history, climatology, land-water interactions, mercury found in the Alaskan arctic, and the response of lakes to environmental change. The final chapter brings together these findings in order to make predictions regarding the consequences that arctic Alaska faces due to global warming and climate change, and discusses the future of the LTER site in the region.Less

Between 1949 and 1955, the State Department pushed for an international fisheries policy grounded in maximum sustainable yield (MSY). The concept is based on a confidence that scientists can predict, theoretically, the largest catch that can be taken from a species’ stock over an indefinite period. And while it was modified in 1996 with passage of the Sustained Fisheries Act, MSY is still at the heart of modern American fisheries management. As fish populations continue to crash, however, it is clear that MSY is itself not sustainable. Indeed, the concept has been widely criticized by scientists for ignoring several key factors in fisheries management and has led to the devastating collapse of many fisheries. This book reveals that the fallibility of MSY lies at its very inception—as a tool of government rather than science. The foundational doctrine of the MSY emerged at a time when the US government was using science to promote and transfer Western knowledge and technology, and to ensure that American ships and planes would have free passage through the world’s seas and skies. The author charts the history of US fisheries science using MSY as her focus, and in particular its application to halibut, tuna, and salmon fisheries. Fish populations the world over are threatened, and this book will help sound warnings of the effect of any management policies divested from science itself.Less

Allee effects are broadly defined as a decline in individual fitness at low population size or density, that can result in critical population thresholds below which populations crash to extinction. As such, they are very relevant to many conservation programmes, where scientists and managers are often working with populations that have been reduced to low densities or small numbers. There are a variety of mechanisms that can create Allee effects, including mating systems, predation, environmental modification, and social interactions among others. The abrupt and unpredicted collapses of many exploited populations is just one illustration of the need to bring Allee effects to the forefront of conservation and management strategies. This book provides an overview of the topic, collating and integrating a widely dispersed literature from various fields: marine and terrestrial, plant and animal, theoretical and empirical, academic and applied.

Elephants have fascinated humans for millennia. Their ivory has been sought after and treasured in most cultures, and they have delighted zoo and circus audiences worldwide for centuries. But it was not until the second half of the twentieth century that people started to take an interest in elephants in the wild, and some of the most important studies of these intelligent giants have been conducted at Amboseli National Park in Kenya. This book provides a summation of what has been learned from the Amboseli Elephant Research Project—the longest continuously running elephant research project in the world. It presents more than three decades of uninterrupted study of over 2,500 individual elephants, from newborn calves to adult bulls to old matriarchs in their 60s. Chapters explore such topics as elephant ecosystems, genetics, communication, social behavior, and reproduction, as well as new developments from the study of elephant minds and cognition. The book closes with a view to the future, making arguments for the ethical treatment of elephants and suggestions to aid in their conservation.Less

This book combines the latest scientific information and one man's personal experience in an homage to one of the most magnificent animals to have roamed America's vast, vanished grasslands. The book relates what is known about this iconic animal's life in the wild and its troubled history with humans. The book takes us on a journey into the bison's past and shares a compelling vision for its future, offering along the way a valuable introduction to North American prairie ecology. The book acquaints us with the social life and physiology of the bison, sharing stories about its impressive physical prowess and fascinating relationships. Describing the entire grassland community in which the bison live, it talks about the wolves, pronghorn, prairie dogs, grizzly bears, and other animals and plants, detailing the interdependent relationships among these inhabitants of a lost landscape. The book also traces the long and dramatic relationship between the bison and Native Americans, and gives a surprising look at the history of the hide hunts that delivered the coup de grace to the already dwindling bison population in a few short years. This book gives us a peek at the rich and unique ways of life that evolved in the heart of America. The book also dismantles many of the myths we have created about these ways of life, and about the bison in particular, to reveal the animal itself: ruminating, reproducing, and rutting in its full glory. This portrait of the bison ultimately becomes a plea to conserve its wildness and an eloquent meditation on the importance of the wild in our lives.Less
